Always use a skin-safe release agent before applying plaster bandages. Never apply plaster directly to skin or hair, as it can cause irritation, burns, or become painfully stuck. Test materials on a small area first if you have sensitive skin.
Preparing for Your Life Casting Session
Proper preparation is crucial for a successful life casting experience. Follow these steps before applying any materials:
Setting Up Your Workspace
Choose a comfortable area with good ventilation and access to water. Cover all surfaces with plastic sheeting or drop cloths, as plaster can be messy. Arrange your materials within easy reach and prepare bowls of warm water (80-90°F) for dipping the bandages.
For optimal results, maintain a comfortable room temperature between 68-75°F. Extreme temperatures can affect setting times and comfort for your model.
Preparing Your Model
Have your subject wear old clothes or cover them with a plastic cape. Explain the process thoroughly so they know what to expect. For areas with hair, apply a generous layer of petroleum jelly or specialized release cream to prevent the plaster from sticking.
Position your model in a comfortable pose they can maintain for 15-20 minutes without moving. Use pillows or supports if necessary to help maintain the position.
Step-by-Step Life Casting Process with Plaster Bandages
Follow this detailed process to create your life cast. We'll break it down into manageable steps that ensure success even for first-time casters.
Step 1: Apply Release Agent
Begin by thoroughly applying your release agent (petroleum jelly or specialized release cream such as MoldEZ) to the area being cast. Pay special attention to body hair, eyebrows, and hairlines. The release agent should form a thin but complete barrier between the skin and plaster.
"The most common mistake beginners make is skimping on release agent. Be generous - it's much easier to apply extra than to deal with plaster stuck to hair."
Step 2: Prepare and Apply Plaster Bandages
Cut your plaster bandages into manageable strips (4-6 inches long). Dip each strip into warm water for 2-3 seconds until bubbles stop forming. Gently run the strip between your fingers to remove excess water without squeezing out the plaster.
Apply the first layer of bandages, overlapping each strip by about 50%. Work quickly but carefully, smoothing as you go to eliminate air bubbles. For most projects, 3-4 layers provides adequate strength.
Pro Tip: For areas with complex contours like fingers or facial features, use smaller strips to ensure the bandages conform properly to the shape.
Step 3: Allow Setting and Curing
The plaster bandages will begin to set within 5-8 minutes, becoming warm and firm to the touch. Allow 15-20 minutes total for proper curing before attempting removal. The cast is ready when it feels completely firm and the warmth has subsided.
During this time, ensure your model remains still. Light conversation can help pass the time and keep them comfortable. Remind them that the warming sensation is normal as the plaster cures.
Step 4: Remove the Cast
Once fully cured, gently work your fingers around the edges of the cast to break the seal. Have your model relax the cast area while you slowly and carefully remove the mold. For complex shapes, you may need to cut a removal line with scissors.
If you encounter resistance, apply more petroleum jelly around the edges and continue working slowly. Never force removal, as this can damage both the cast and potentially hurt your model.
Step 5: Prepare for Casting (Optional)
If you plan to create a positive cast from your mold, allow the plaster bandage mold to dry completely (24 hours is ideal). Once dry, apply a thin layer of petroleum jelly or soap solution as a release agent inside the mold.
You can then pour your casting material (plaster, resin, etc.) into the mold and allow it to set according to the material's instructions. After curing, carefully remove the outer bandage mold to reveal your finished cast.

Safety Precautions for Life Casting
Safety should always be your top priority when creating life casts. Follow these essential precautions:
Essential Safety Measures
- Skin Protection: Always use a generous layer of release agent on all skin and hair that will contact plaster.
- Breathing Protection: When casting faces, ensure nostrils remain clear. Never cover both nostrils.
- Temperature Awareness: Monitor the heat generated during curing. If it becomes uncomfortably hot, remove immediately.
- Ventilation: Work in a well-ventilated area, especially when mixing plaster or using alginate.
- Allergies: Test materials on a small skin area first if you're concerned about allergic reactions.
- Supervision: Never leave someone alone while they have plaster bandages applied to their face or body.
What to Avoid
- Direct Application: Never apply plaster directly to skin without a release agent.
- Enclosed Areas: Avoid completely enclosing any body part (always leave an opening).
- Excessive Thickness: Don't apply too many layers, as this increases heat and weight.
- Rushing Removal: Never force removal before complete curing.
- Sensitive Areas: Avoid casting extremely sensitive skin or areas with wounds.
- Prolonged Sessions: Don't keep someone in a casting position for too long.
Finishing and Decorating Your Life Casts
Once your cast has fully dried (24-48 hours for larger pieces), you can transform it into a beautiful finished piece with these techniques:
Sanding and Smoothing
Start with medium-grit sandpaper (120-150) to remove major imperfections, then progress to finer grits (220-320) for a smooth finish. Sand in circular motions, being careful not to apply too much pressure. Wipe away dust frequently with a slightly damp cloth.
For hard-to-reach areas, use small pieces of sandpaper wrapped around a pencil or dowel. Take your time with this step—it creates the foundation for all further finishing.
Painting Techniques
Before painting, apply a thin layer of gesso or primer to create a smooth, receptive surface. Acrylic paints work best on plaster, offering vibrant colors and easy cleanup. Consider these approaches:
- Solid Color: A single color creates a classic, sculptural look
- Metallic Finish: Gold, silver, or bronze paints for an elegant appearance
- Faux Stone: Sponge on multiple colors for a marble or granite effect
- Realistic: Flesh tones and details for a lifelike appearance
Sealing for Longevity
To protect your finished piece, apply a clear sealer. Options include:
- Acrylic Sealer: Available in matte, satin, or gloss finishes
- Polyurethane: Provides durable protection for frequently handled pieces
- Wax: Creates a soft, natural-looking finish with subtle sheen
Apply 2-3 thin coats rather than one thick coat, allowing proper drying time between applications. This ensures even coverage and prevents drips or bubbles.
Display Options
Consider these creative ways to display your finished life casts:
- Mount on a wooden base or plaque with felt backing
- Hang on walls using picture hanging hardware
- Create a shadow box display with meaningful items
- Use as functional pieces (hand casts as jewelry holders, etc.)

Troubleshooting FAQ for Life Casting with Plaster Bandages
Even experienced artists encounter challenges. Here are solutions to common issues:
How do I prevent air bubbles in my cast?
Air bubbles typically occur when bandages aren't smoothed properly during application. To prevent them:
- Work methodically, smoothing each strip as you apply it
- Use your fingers to press bandages into detailed areas
- Avoid rushing the application process
- For very detailed areas, consider using alginate first, then reinforcing with plaster bandages
Why is my plaster taking too long to dry?
Several factors can affect drying time:
- High humidity slows drying (use a fan or dehumidifier)
- Water temperature was too cold (use 80-90°F water)
- Too much water remained in the bandages (gently remove excess)
- Bandages were applied too thickly (use thinner, more even layers)
To speed drying, place the cast in a warm, dry area with good air circulation.
How can I preserve fine details in my life cast?
For capturing intricate details:
- Consider using alginate as a first layer before applying plaster bandages
- Cut bandages into smaller strips for detailed areas
- Use your fingertips to press bandages into creases and contours
- Apply thinner layers rather than fewer thick ones
- Allow complete curing before removal to prevent warping
What if the cast sticks to skin or hair?
If your cast is sticking during removal:
- Don't force it – this can cause pain and damage the cast
- Apply additional petroleum jelly around the edges
- Work your fingers gently around the perimeter to break the seal
- Use warm water to help dissolve any areas stuck to hair
- For future casts, apply a thicker layer of release agent
How do I fix cracks in my finished cast?
To repair cracks in dried plaster casts:
- Mix a small amount of plaster of Paris to a creamy consistency
- Slightly dampen the cracked area
- Fill the crack with the fresh plaster using a small tool
- Smooth the surface and allow to dry completely
- Sand the repaired area to blend with the surrounding surface
Can I make a two-part mold for complex shapes?
Yes, for complex shapes like a full face or torso:
- Create a dividing line using clay or a similar material
- Cast one side first, creating registration keys (indentations)
- Apply release agent to the edges of the first half
- Cast the second half, allowing it to interlock with the first
- This technique requires practice but allows for casting complex forms
